Abstract

PURPOSE:To enable the alignment of goods to be aligned with a reduced energy loss and independently of the size and shape of goods to be aligned by forming a groove which communicates the bottom plate of a transport box provided to a rotary body with the nearly center of the closing plate, and also arranging a discharge pin in the groove passing position. CONSTITUTION:A rice cookie dough A fed to a parallel conveyor 1 is transferred to the end of the conveyor 1, and is stopped there. As soon as a transport box 5 is brought to the position of a chute 2 by the rotation of a rotary body 7, a motor 4 is immediately driven, and the rice cookie dough A is thrown into the inside of the transport box 5 through the chute 2 from the conveyor 1. Then, as the rotary body 7 rotates, the rice cookie dough A moves by gravity to the end part of the transport box 5, and is positioned on the place where a groove is provided. When the rotary body 7 further rotates, and the transport box 5 reaches the lowest passing position, a discharge pin 8 intrudes into the inside of the groove to push out the rice cookie dough A to the opening part on the outer circumferential side to drop it down, so that the dough is transferred onto a baking conveyor 9. Thus, the rice cookie doughs A can be aligned on the baking conveyor 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an alignment and feeding device for aligning and feeding articles to a conveyor, and is mainly used in the production of rice crackers.

(Prior Art and Problems to be Solved by the Invention) To explain the production of rice crackers by taking as an example the production of rice crackers using unhulled rice as a raw material, there are a rice washing process and a flour milling process.

The dough is formed through a steaming process, kneading process, cooling process, rolling die cutting process, and then a dough drying process.

Baking process, seasoning process, finishing] - Drying process, packaging process, and then shipped.

The need for alignment and supply in the manufacturing process is during the firing process.
The baking process is carried out by arranging the rice cracker dough on a mesh-shaped baking conveyor and passing it through a baking furnace to tighten it.Since the rice crackers expand during baking, it is necessary to prevent them from sticking to each other and to bake them efficiently. The rice cracker dough must be lined up in an orderly manner on the baking conveyor with a predetermined spacing so that the baking process can be achieved.

The most common conventional aligning and feeding means includes a stacking section a for aligning rice cake dough and a baking conveyor b, as illustrated in FIG.
A rotary body d having a large number of suction nozzles C arranged radially and in parallel is provided between the laminated part a and the dough, which suctions the dough to the suction nozzles, rotates it to the baking conveyor IJ, and then suctions it to the detachment part C. The dough is separated from the nozzle C and arranged on the baking conveyor b. However, since seven suction nozzles are used, a large-capacity suction blower is required, resulting in high cost and large energy loss. The suction nozzles may become clogged, requiring maintenance, and may not be properly aligned.

In addition to the suction nozzle method mentioned above,
As shown in Publication No. 0019, there is also an alignment device that generally feeds the fabric with a push pin that moves in the center of the guide path, regulates the layer thickness during the conveyance, and eliminates stacking due to inclination. As is known, this method cannot be applied to rice cracker dough of different sizes and thicknesses, and cannot be used as a general-purpose device and is not flexible.

(Means for Solving the Problems) In view of the above-mentioned problems, the present invention proposes an alignment and supply device that is versatile and reduces running costs.

The aligning and feeding device according to the present invention has an arrangement in which an appropriate number of carrying boxes are arranged in parallel in the radial and axial direction on the outer circumferential portion between the supplying section located above and the aligning and carrying section located below. In addition to the arrangement of the rotary body, a groove is provided which closes the rotational direction side of the open portion on the outer circumferential side of the transport box, and communicates the bottom plate and the approximate center of the closing plate along the rotational direction. The apparatus is characterized in that a discharge pin is arranged at a groove passing position when the transport box passes below the rotating body.Furthermore, in the above-mentioned aligning and feeding device, the transport box is placed on the rotation direction side of the transport box. It has a tapered shape.

Furthermore, in the above-mentioned alignment and supply device, the supply section is composed of a parallel conveyor that corresponds to the transport box (7. Each conveyor is driven independently, and a sensor is installed at the tip of the conveyor, so that when the objects to be arranged are sensed, the conveyor Stop the drive and put it in standby state,
The feature is that the closing operation is performed all at once in synchronization with the rotation of the rotating body.

(Function) Supply section J: When the objects to be arranged (rice cracker dough) are put into the transport box, as the objects to be arranged (rice cracker dough) rotate, the tip of the transport box (rotating direction) and is located between the closing plate and the bottom plate.As the rotation progresses further and it reaches the lowest point, it is pushed out from the closing plate to the opening on the outer circumferential side by the ejection pin, and the alignment conveying part (for baking Since the transport boxes are arranged in parallel in the axial direction of the rotating body and are arranged radially, they are arranged in an orderly manner at equal intervals on the alignment transport section.

In addition, if the transport box is tapered, when transporting the items to be sorted,
The objects to be aligned will always fall to the predetermined position of the tapered part, so
When aligned, the horizontal rows form a straight line.

Furthermore, in the supply section, the objects to be sorted stop at the tip of the parallel conveyor and are thrown into the transport box all at once, so even if there is a slight time difference for each parallel cono pair, they are thrown into the transport box at the same time. It is something.

(Example) Next, as an example of the present invention, an alignment and supply apparatus for supplying rice cracker dough to a baking furnace will be explained.

The aligning and feeding device is composed of a feeding section located on the -1 side, an aligning conveying section located below for carrying the rice cake dough into the baking furnace B, and a rotating conveying section provided between the two. The supply section consists of a parallel conveyor 1 that is driven independently and receives the supply of rice cracker dough, and a chute 2 that throws the rice cracker dough from the parallel conveyor 1 into a transport box to be described later. A sensor 3 is attached to the conveyor, and a drive motor 4ie of the parallel conveyor is controlled by a signal from the sensor 3 and a synchronization signal from a rotary conveyance section, which will be described later. The rotary conveyance unit includes a rotary body 7 in which the conveyance boxes 5 are arranged in parallel in a manner corresponding to the number of the parallel conveyors 1, and is arranged radially around a rotating shaft 6, and a fixed discharge pin 8, and the conveyance boxes 5 The tail part of the outer peripheral side part is open, but the tip part (rotation direction side) is provided with a closing plate 51, the tip part is formed into a tapered shape, and the closing plate 51 and the bottom plate are provided at the center of the tip part. 52 in the rotational direction, and the ejection pin 8 is provided in the passage space of the groove 53 at the lowest passage position of the transport box 5. The alignment conveyance section is a mesh-like baking conveyor 9 that moves into the baking furnace B, and is provided close to the lowest passage position of the transportation box 5.

When rice cracker dough A is supplied to the parallel conveyor,
The rice cracker dough is conveyed to the tip of the conveyor 1 and stopped. That is, when the sensor 3 senses the presence of rice cracker dough, the conveyor 1 stops, and even if the rice cracker dough is supplied to each conveyor 1 irregularly, the rice cracker dough A waits at the tip of the conveyor. The rice cracker dough conveyance of each conveyor 1 is unified in time as a state in which the conveyor 1 is in a state where the conveyor box 5 is brought to the position of the chute 2 by the rotation of the rotary body 7, and a signal from the rotary conveyance section is transmitted to the motor 4. At the same time, the motor 4 is driven, and the rice cracker dough A is fed from the conveyor 1 through the chute 2 into the transport box 5.As the transport box 5 is moved as the rotating body 7 rotates, the rice cracker dough A is transferred.
moves by its own weight to the tapered tip of the transport box 5 and is located at a predetermined location, that is, a location between the closing plate 51 and the bottom plate 52 and where the groove 53 is provided. When the rotating body 7 further rotates and the transport box 5 reaches the lowest passing position, the discharge bin 8 enters into the groove 53 and pushes out the rice cracker dough A from the position of the closing plate 51 to the opening on the outer peripheral side. The rice cracker dough A falls from the transport box 5 and is transferred onto the baking conveyor 9. Therefore, the rice cracker dough A is transferred to the baking conveyor at a lateral spacing corresponding to the lateral spacing of the transportation box at the lowest passing position, and at a longitudinal spacing corresponding to the moving distance of the baking conveyor 9 in one pitch movement time of the transportation box 5. 9 and place them in alignment.
